  • Patent number: 9097084
    Abstract: A system and methodology facilitates an operation utilizing coiled tubing. The technique comprises coupling a hydraulic assist device to coiled tubing. A fluid is flowed into an enclosure such as a wellbore and along the coiled tubing. The fluid is flowed against the hydraulic assist device, and the action of this fluid against the hydraulic assist device creates a pulling force on the coiled tubing. The pulling force facilitates movement of the coiled tubing along the wellbore or other enclosure to provide the coiled tubing with greater reach for a variety of intervention operations or other types of operations.

    Abstract: A fracturing jet nozzle assembly features a series of angles nozzles on a rotatably mounted plate that operates in conjunction with a central nozzle or nozzles. The slanted nozzles are aimed into the perforation where the central nozzle is aimed directly so that the rotation of the nozzle plate from the slanted nozzles results in cyclic impacts in the perforation from where the fractures will propagate. The cyclic loading results in greater fracture formation and propagation. In another variation, relatively movable plates employing slanted nozzles rotate one plate with respect to another to get the effect of cyclic pulses of jetting fluid impingement in the perforation to enhance formation and propagation of fractures from the perforation.

Varying the nozzle geometry remotely without the need to pull the drill string outside the hole has obvious advantage. Changing the nozzle glow geometry results in changing the nozzle HSI which is beneficial to optimize drilling different rock formations in different drilling environment. There are many concepts to vary the nozzle size while drilling. The drill bit nozzle geometry can be varied by causing a change of at least one physical property of the environment. The variable geometry nozzle is not limited to drill bit, it can be placed within the inner flow passage or between the inner flow passage and annular flow passage for controlling flow profile within a wellbore, a tubular string or a flow conduit.

  • Patent number: 8403049
    Abstract: A tubing conveyed tool for use in perforating a well bore utilizing abrasive perforating techniques. The perforating tool is particularly useful in non-vertical wells. The perforating tool is designed to permit running and setting a bridge plug, and then perforating the well bore without requiring the removal of the tool string. An eccentric weight bar can also be used to allow for directional perforating in non-vertical wells. The eccentric weight bar uses gravity to cause the bar to rotate to a predetermined position.

  • Patent number: 8376038
    Abstract: An outlet member is preferably made from a hardened material and is cut from a tubular shape at an angle of preferably 5 degrees. At its upper end it is cut away so that slurry flow can exit ports in a hardened sleeve and impinge directly onto the upstream portion of the insert. The impingement changes the flow stream angle as the flow continues through a fully tubular middle segment of the insert that leads out to an elongated exit ramp whose downstream end sits preferably flush with the outer housing wall so as to protect the insert from mechanical shocks and retain the insert axially when slurry flows through it. Other external details aid in fixation when in use.

  • Patent number: 8371369
    Abstract: A crossover tool that resists the erosive forces of high velocity slurry streams of gravel in downhole fracturing and gravel packing operations employs hardened inserts that protect the inside face of the housing as well as the openings through the crossover housing wall. The inserts have an extending portion that goes through housing openings preferably to the outer surface of the housing. The inserts also have inboard flanged surfaces that preferably abut or overlap to give preferably full inner wall protection to the housing from the flow of abrasive slurry. The inserts can be secured to each other or to the interior of the housing to hold them firmly in place.

  • Patent number: 8365827
    Abstract: A series of jet nozzles have a telescoping structure designed to impact the borehole wall and initiate a fracture. The nozzles can be extended through fluid pumped through them or with some mechanical force from within the bottom hole assembly. The leading ends of the telescoping assembly can be sharp and hardened to facilitate the initiation of a formation fracture in an open hole. The telescoping structures can be disposed in a single or multiple rows with the circumferential spacing being such that each telescoping structure is designed to cover a target circumferential distance of 45 degrees or less so that jetted fluid from at least one jet will be within 22.5 degrees of a location of maximum formation stresses to reduce the tortuosity of the created fractures from jetting through the nozzles with possible enhancement of the fracturing from added annulus pressure.

  • Publication number: 20130008647
    Abstract: A method for modifying a return fluid in a wellbore comprising disposing at least one valve along a drill pipe section of a drill string in the wellbore. At least one parameter of interest is determined at at least one location along the wellbore. At least one valve is controllably actuated to discharge at least a portion of at least one fluid from inside the drill string to an annulus in the wellbore to modify a local property of the return fluid in the annulus based at least in part on the measured parameter of interest.

  • Publication number: 20130000888
    Abstract: The invention provides for a jetting tool for use with a drillstring. The tool generally includes a tubular main body having an inlet and an outlet arranged in fluid communication via a fluid conduit, the main body defining at least one aperture along its length. The tool also includes an elongate outer ring assembly configured for fitment about the main body to enclose the at least one aperture. This ring assembly defines an upper circumferential fluid port and a lower circumferential fluid port, each port configured to operatively direct fluid towards the other. The tool also typically includes a valve assembly receivable inside the fluid conduit, the valve assembly displaceable between a drilling position, wherein fluid is able to pass from the inlet to the outlet via the fluid conduit, and a jetting position, in which fluid is diverted from the inlet to the upper and lower fluid ports via the aperture.

  • Publication number: 20120312539
    Abstract: A method and apparatus for cleaning a water well is presented. The apparatus utilizes a tool body having a plurality of discharge nozzles for jetting streams of filtered water at high pressure on to the inside wall surface of a casing across a water zone having slots or perforations. The nozzle streams are offset from the tool body imparting a rotational force. A rotary coupling is also utilized to limit the maximum rotation. The apparatus is lowered by a pre-determined length of coiled tubing to cleaning depth after which it is raised at a slow rate across the water zone.

  • Publication number: 20120312536
    Abstract: An assembly for performing multiple downhole hydraulic stimulation applications in a well. The different applications may be performed without removal of the assembly from the well between the different applications. So, for example, even a hydraulic perforating application may be performed with prior or subsequent clean-out applications. Yet, there is no need to remove the assembly for manual surface adjustment of the hydraulic perforating tool in order to allow for such clean-outs. Thus, the time to run such multi-stage stimulation operations may be dramatically reduced.

  • Patent number: 8322418
    Abstract: A slurry discharge device for use in a subterranean well can include a slurry flow passage extending longitudinally in the device. The slurry flow passage has flow passage sections. One flow passage section is positioned downstream of, and is laterally offset relative to, another flow passage section. Another slurry discharge device can include the slurry flow passage having multiple flow areas. One flow area is positioned in a downstream direction from, and is greater than, another flow area. A method of delivering a slurry into a subterranean well can include discharging the slurry from a tubular string through a first sidewall section of a slurry discharge device; and flowing only a returned fluid portion of the slurry through a second sidewall section of the slurry discharge device. The second sidewall section has a lateral thickness greater than a lateral thickness of the first sidewall section.
